BUG: Seeming Memory Leak

When using the UI to perform multiple different database comparisons the working memory set continues to grow in Windows. After performing 8-10 database to database comparisons back to back, the working memory set had grown from 300-400 MB to about 3.5 GB.

I have verified that the program is up to date (version 13.1.11.5591 at this time) and it is running on Windows 7 Pro 64-bit.

    I can confirm I have been seeing this as well, but with SQL Data Compare v13. At one point I had it consuming over 33 GB. emusvyj6jwnh.png. It was fairly easy for me to reproduce (though in all fairness it was against a database which had four tables that had 1.8 million records)
    - Run compare on large table #1 (~1.8 million records)
    - Generate script
    - Deploy script
    - Run compare on large table #2 (~1.8 million records)
    - Generate script
    - Deploy script
    - Memory usage will be fairly large at that point

    Aside from restarting the tool, I can't provide a better answer. All that I can say is I have seen this happen as well, typically with Data Compare, but it is not uncommon with SQL Compare either.
